HORSESHOE-OALK.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Application filed June 15, 1905. serial No. 265,394.

My invention relates to calks for use onany style or type of horseshoe,but particularly adapted for draft-horses.

The object of my invention is to provide a calk which can be easily andquickly placed on the shoe or removed without taking the shoe off thehorses foot.

The invention consists generally in providing the heel of the shoe withthreaded studs or extensions adapted to enter sockets in the shoe-calkand having lock-nuts for locking the calk securely on the stud.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective view of a horseshoe with my invention appliedthereto. Fig. 2 is a bottom view of the same. Fig. 3 is a detailsectional view on the line a; m of Fig. 2. Fig. 4 is a sectional view onthe line 1 y of Fig. 3, and Fig. 5 is an edge view of the shoe.

In the drawings, 2 represents a horseshoe adapted particularly for adrafthorse, the heel of the shoe terminating on each side in a squaredshank 3, having a threaded extension 4 for a lock-nut 5. The calk 6 hasa square socket 7 to receive the shank 3, and the calk is held on theshank by means of the lock-nut 5 and can be readily placed thereon orremoved without taking the shoe off the horse s foot. The end of thecalk 6 is wedgeshaped, as shown, and mounted on the shoe substantiallyat right angles to the draft-line,

and therefore forms a wide edge to dig into the ice and prevent thehorse from slipping while drawing the load. The ordinary removabletoe-calk has a round point, and, while suitable for driving or racinghorses, is not ada ted for a draft-horse, where it is necessary for thecalk to have a broad contact on the ice or snow to revent slipping. Theshanks 3 project asu cient distance beyond the hoof to allow the calksto be readily rei moved or placed on the shoe without in any waydisturbing the position of the shoe on the hoof. The calks are providedwith recesses on one side, as shown in Fig. 1, forming shoulders whichsupport the heel of the shoe and relieve the shank of a considerableportion of the strain.

I claim as my invention 1. The combination, with a horseshoe provided onits heel with a threaded extension, of a calk having a socket to receivesaid eX- tension, and a lock-nut for said extension, substantially asdescribed.

2. The combination, with a horseshoe having its heel terminating in asquared shank, of a calk having a wedge-shaped wearingsurface and asocket to receive said shank, said calk having a recess on one sideforming a shoulder and a bearing-surface for the heel of the shoe, andmeans for securing said calk on said shank.

In witness whereof I have hereunto set my hand this 9th day of June,1905.
